In China, the traditional calendar is known as the "agricultural calendar" (traditional Chinese: 農曆; simplified Chinese: 农历; pinyin: nónglì) while the Gregorian calendar is known as the "common calendar" (traditional Chinese: 公曆; simplified Chinese: 公历; pinyin: gōnglì). Another name for the Chinese calendar is the "Yin Calendar" (traditional Chinese: 陰曆; simplified Chinese: 阴历; pinyin: yīnlì) in reference to the lunar aspect of the calendar, whereas the Gregorian calendar is the "Yang Calendar" (traditional Chinese: 陽曆; simplified Chinese: 阳历; pinyin: yánglì) in reference to its solar properties. The Chinese calendar was also called the "old calendar" (traditional Chinese: 舊曆; simplified Chinese: 旧历; pinyin: jiùlì) after the "new calendar" (traditional Chinese: 新曆; simplified Chinese: 新历; pinyin: xīnlì), i.e., the Gregorian calendar, was adopted as the official calendar. For more than two thousand years, since the time of Emperor Wu of Han the month containing the winter solstice has almost always been the 11th month. (This means the new year starts on the second new moon after the winter solstice unless there is an 11th or 12th intercalary month, in which case it starts on the third new moon.) A calendar using this new year is often referred to as "the Xia Calendar" (traditional Chinese: 夏曆; simplified Chinese: 夏历; pinyin: xiàlì), following a comment in the Shiji which states that under the Xia Dynasty, the year began on the second new moon after the winter solstice. At times under some other dynasties in ancient China, the month with the winter solstice was the 12th or the 1st month.

The year 2011 in the Chinese calendar is the Year of the Rabbit. It began on February 3, 2011 and will end on January 22, 2012. According to traditional beliefs, some form of the calendar has been in use for almost five millennia. Based on archaeological evidence some form of it has been in use for three and a half millennia. The year 2011 is reckoned in the seldom-used continuously numbered system as 4708 or 4648 (depending on the epoch used, see Continuously numbered years).

These arbitrary rules on day and month intercalation caused the calendars of each state to be slightly different, at times. Thus, texts like the Annals will often state whether the calendar they use (the calendar of Lu) is in phase with the Royal calendar (used by the Zhou kings).

In 256 BCE, as the last Zhou king ceded his territory to Qin, a new calendar (the Qin calendar) began to be used. It followed the same principles as the Sifen calendar, except the year began one month before (the second new moon before the winter solstice, which now fell in the second month of the year). The Qin calendar was used during the Qin dynasty, and in the beginning of the Western Han dynasty.
